The distribution of quality characteristic of a product is usually assumed to be known. In some situation, the quality characteristic of a product cannot be measured directly. It needs to be measured by controlling another factor. Wen and Mergen (1999) presented a method for determining the optimum process mean in order to minimize the expected total loss of a product. However, they have not considered the quality loss for a product within specification in the model. In this paper, we will propose a modified Wen and Mergen’s (1999) model taking into account an indirect quality characteristic with the quadratic or linear asymmetrical quality loss of a product within specifications.
